FYI: I found a solution for my recent problem with the extra buttons of a thinkpad tablet:
xinput set-int-prop 13 "Device Enabled" 8 0 13 in my case is the ID of the extra buttons. If you have problems with a similar device, this webpage might help: https://thinkwiki.de/Linux_auf_X-Serie_Tablets#Tablet-Tasten_konfigurieren- Unfortunately it's German. Thanks & All best to you!
